Description

Technical Field

[0001] The invention relates to a notebook computer. Background Art

[0002] When working, electronic devices such as laptops generate a lot of heat and cause the temperature to rise. If the temperature cannot be dissipated quickly, it will not only cause the device to crash, but also reduce the service life of the components in the device if they are in a high temperature environment for a long time. In order to keep the temperature of the electronic device within a normal range, the common practice in the industry is to install fans or heat sinks in the electronic device to help dissipate heat.

[0003] However, after long-term use, a large amount of dust will accumulate on the fan impeller or the cooling fins, thus affecting the cooling effect. The existing solution with the best cleaning effect still relies on removing the fan for manual cleaning. However, this requires users to face the complicated process of disassembling and assembling the electronic device (such as the aforementioned laptop), which reduces the user's sense of operation and experience. Summary of the invention

[0004] The invention is directed to a notebook computer, which provides a simple casing structure and is convenient for users to operate to clean the inside of the computer.

[0005] According to an embodiment of the present invention, a laptop computer includes a host, a movable door, a screen, an input module, and a fan. The host has a first surface and a second surface opposite to each other. The movable door is disposed on the second surface. The screen is pivotally connected to the host to be closed on the first surface or unfolded from the first surface. The input module is disposed on the first surface. The fan is disposed in the host, and the movable door covers the fan. After the movable door moves away from the fan, the impeller of the fan is exposed from the host from the second surface.

[0006] Based on the above, the notebook computer sets a movable door on the second surface of the main body, and the fan configured in the main body is covered by the movable door. Accordingly, the user can easily operate the movable door to cover the fan or remove it from the fan. After removing the movable door, the impeller of the fan can be exposed to the main body through the second surface, and the user can perform the required cleaning operation on the impeller to improve the heat dissipation efficiency of the fan. In other words, due to the setting of the movable door on the second surface, the main body can provide the user with a simple mechanism to clean the fan, and the user does not need to worry about the complicated process of disassembling and assembling the main body structure affecting its operation and experience.

[0020] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0021] Figure 1A FIG. 4 is a schematic diagram of a notebook computer according to an embodiment of the present invention. Figure 1B Shown from another perspective Figure 1A The main unit of the laptop computer is shown in Figure 1, and some components are omitted here. Please also refer to Figure 1A and Figure 1BIn this embodiment, the notebook computer 100 includes a host 110, a screen 130, an input module 120, and a fan 140. The host 110 has a first surface S1 and a second surface S2 opposite to each other. The screen 130 is pivotally connected to the host 110 to be closed on the first surface S1 or unfolded from the first surface S1. The input module 120 includes, for example, a touch pad and a keyboard, which are disposed on the first surface S1. The fan 140 is disposed in the host 110.

[0022] Figure 2A yes Figure 1B Schematic diagram of the host computer. Figure 3A yes Figure 1B A partial schematic diagram of the host in another state. Please also refer to Figure 2A and Figure 3A The notebook computer 100 of this embodiment further includes a movable door MD, which is disposed on the second surface S2 and is used to cover the fan 140. After the movable door MD is moved away from the fan 140, the impeller 142 of the fan 140 is exposed from the second surface S2 to the host 110. In this way, the user can clean or even repair the fan 140 inside the host 110 by opening the movable door MD without having to consider the problem of disassembling the structure of the host 110.

[0023] Figure 2B Shown from another perspective Figure 2A some components of . Figure 2C Show Figure 2B The state of overlapping parts in the middle. Please also refer to FIG. 2A to FIG. 2C In this embodiment, a movable first door 112 is disposed at the bottom of the host 110 (i.e., at the second surface S2), which is movably pivoted to the arc track 111 of the host 110. The fan 140 includes a second door 141, the impeller 142 and a base 143, wherein the impeller 142 is rotatably disposed on the base 143, and the second door 141 is pivoted to the base 143, so that the movable door MD of this embodiment actually includes the arc track 111, the first door 112, the second door 141 and parts of the base 143.

[0024] In detail, Figure 2A As shown, the first door 112 has a pivot shaft portion 112a for being movably pivoted to the arc track 111, and for the fan 140, its base 143 includes a bottom plate 143a, a side wall 143b, a pivot shaft portion 143c, a positioning hole 143d and a support column 143e, wherein the side wall 143b stands on the bottom plate 143a, and the pivot shaft portion 143c extends from the side wall 143b in a direction away from the impeller 142, and is used to be pivotally connected to the pivot shaft portion 141c of the second door 141. A positioning hole 143d is provided in a part of the side wall 143b, and the support column 143e stands on the periphery of the bottom plate 143a.

[0025] Figure 2D yes Figure 2A Sectional view of some components after assembly. Please refer to FIG. 2B to FIG. 2D In this embodiment, the pivot side of the first door 112 and the pivot side of the second door 141 are actually two different but parallel pivot axes, and they need to be linked to each other. Therefore, the end E1 of the second door 141 away from the pivot fan 140 is slidably coupled to the first door 1121. Figure 2B and Figure 2C As shown, the first door member 112 has a pair of L-shaped limiting protrusions 112b, and the opposite sides of the second door member 141 are movably coupled to the limiting protrusions 112b. Therefore, the second door member 141 is restricted by the limiting protrusions 112b and is partially in constant contact with the first door member 112. Figure 2A , Figure 2C and Figure 2D When the movable door MD is closed on the second surface S2 of the host 110, the buffer member P1 abuts between the first door member 112 and the second door member 141, and there is a gap G1 between the first door member 112 and the second door member 141. In other words, the first door member 112 presses the second door member 141 through the buffer member P1. Figure 2A and Figure 2B The base 143 of the fan 140 has the aforementioned positioning hole 143d, and the second door 141 has a positioning column 141d. Therefore, when the first door 112 applies pressure to the second door 141 through the buffer P1, the second door 141 is fixed to the base 143 by the positioning column 141d and the positioning hole 143d corresponding to each other. The support column 143e is pressed against the second door 141 to maintain the air outlet of the fan 140. In contrast, this embodiment also uses another buffer (buffer P2) to allow the base 143 to maintain a gap with the structure of the host 110 to ensure that another air inlet (such as Figure 2B As shown, the airflow at the air inlet surrounded by the buffer member P2 can smoothly enter the fan 140. Here, the buffer members P1 and P2 of the present invention are, for example, rubber washers.

[0026] In the present embodiment, since the fan 140 is a centrifugal fan and the second door member 141 is the upper shell structure of the centrifugal fan and has an air inlet 141a, the corresponding relationship among the first door member 112, the buffer member P1, the second door member 141 and the base 143 when closed can not only ensure the space required for the operation of the fan 140 without causing air leakage, but also the gap G1 between the first door member 112 and the second door member 141 can effectively provide an isolation effect for the noise generated by the operation of the impeller 142.

[0027] It should be mentioned that in order to ensure the airtightness of the buffer member P1 between the first door member 112 and the second door member 141 , the second door member 141 of this embodiment further has the aforementioned groove 141 b facing away from the impeller 142 to accommodate a portion of the buffer member P1 .

[0028] Figure 3B Show Figure 3A Sectional view of some components. Please also refer to Figure 2D , Figure 3A and Figure 3B , to provide a comparison for the movable door MD when it is opened and closed. In this embodiment, because the first door member 112 and the second door member 141 are in a state of sliding coupling with each other on the opposite side away from the pivoting point, they have the motion characteristic of being able to slide relative to each other during the process of pivoting, so that when the first door member 112 is opened from the second surface S2 of the main unit 110, the second door member 141 can be opened at the same time to expose the impeller 142 therein. Figure 3B As shown, in the unfolded state, the gap G1 between the first door member 112 and the second door member 141 is in an unequal distance state.

[0029] Based on the above, the movable door MD includes a first door member 112 and a second door member 141, which are respectively pivotally connected to the main unit 110 and the base 143 of the fan 140, wherein the side of the first door member 112 away from the pivotal end is also slidably coupled to the side of the second door member 141 away from the pivotal end. In this way, when the user drives the first door member 112, the second door member 141 can also be driven, so that the impeller 142 of the fan 140 can be exposed from the main unit 110 from the second surface S2 when the movable door MD is opened, so that the user can clean the impeller 142 by only opening the movable door MD.

[0030] Figure 4A Schematic diagram of a fan and a movable door according to another embodiment. Figure 4B and Figure 4C Shown from different perspectives Figure 4A Please also refer to FIG. 4A to FIG. 4C , which is different from the previous embodiment, the movable doors of this embodiment are fixedly connected to each other, and the first door member 212 is assembled to or removed from the mainframe 110 through a tenon structure, wherein the relative positions of the mainframe 110 and the first door member 212 are the same as those of the previous embodiment, so the mainframe 110 is no longer shown in the drawings of this embodiment, and the second door member 241 is fixed to the inner side of the first door member 212, so that it can be assembled to or removed from the base 143 of the fan 140 when the user disassembles the first door member 212. It should also be mentioned that the same components or structures in this embodiment and the previous embodiment are marked with the same symbols, and their contents have been seen in the description of the previous embodiment.

[0031] Further, if Figure 4B and Figure 4C As shown, the first door member 212 has a plurality of unequal diameter protrusions, which include a neck C2 with a smaller outer diameter and a head C1 with a larger outer diameter, and the second door member 241 has a plurality of gourd holes 241a, which include an inner hole H1 and an inner hole H2 that are connected to each other, wherein the inner diameter of the inner hole H1 is greater than the inner diameter of the inner hole H2, and the inner diameter of the inner hole H1 is greater than the outer diameter of the head C1, the outer diameter of the head C1 is greater than the inner diameter of the inner hole H2, and the outer diameter of the neck C2 is smaller than the inner diameter of the inner hole H2. In this way, the unequal diameter protrusion is suitable for being inserted into the inner hole H1 of the gourd hole 241a, and then moving to the inner hole H2, so that the unequal diameter protrusion can be locked in the inner hole H2 due to the corresponding relationship between the inner diameter and the outer diameter, so that the second door member 241 and the first door member 212 are fixed together. In this way, the first door 212 and the second door 241 fixedly connected to each other can be driven by the user to be removed from the main unit 110 , thereby achieving the same effect as in the above embodiment in that the impeller 142 is exposed from the main unit 110 to facilitate cleaning.

[0032] Furthermore, the present embodiment further includes a buffer member P1a abutting between the first door member 212 and the second door member 241 and surrounding an opening 241b of the second door member 241 (equivalent to one of the air inlets of the fan) to keep the gap between the first door member 212 and the second door member 241 equidistant.

[0033] Figure 5A It is an exploded schematic diagram of a fan and a movable door according to another embodiment. Figure 5B Shown from another perspective Figure 5A Please also refer to Figure 5A and Figure 5B , and the aforementioned FIG. 4A to FIG. 4C Compared with the embodiment shown, the movable door of this embodiment also adopts the first door member 312 and the second door member 341 fixed together, but the difference is the means of fixing. In this embodiment, at least one of the first door member 312 and the second door member 341 is made of magnetic material, and this embodiment also includes at least one magnetic member (taking two magnetic members M1 as an example) to magnetically attract and fix the first door member 312 and the second door member 341 together through the magnetic member M1. Figure 5B As shown, the first door member 312 has a plurality of grooves 312a, 312b to accommodate the magnetic member M1, and similarly, this embodiment includes a buffer member P1b to abut between the first door member 312 and the second door member 341 to maintain an equidistant gap. In addition, the first door member 312 of this embodiment also provides a limit for the buffer member P1b through a rib 312b.

[0034] Figure 6FIG. 1 is a simple schematic diagram of a fan and a movable door of another embodiment. Similarly, the same symbols are used in this embodiment to represent the same structures or components as those in the above. Please refer to FIG. Figure 6 Unlike the above-mentioned movable door which is composed of two door members, the movable door of this embodiment has only a single door member 412, which actually forms a part of the second surface S2. Figure 6 As shown, the door member 412 of this embodiment is detachably assembled on the second surface S2 of the host 410, wherein the disassembly and assembly means may refer to the aforementioned embodiment. Of course, this embodiment may also be connected to the host 410 by the pivoting means of the aforementioned first door member 112. As shown by the arrow in the figure, the fan of this embodiment is also a centrifugal fan, which, after taking in air through the axial inlet, will discharge air radially to dissipate heat to the heat dissipation module 420 (e.g., heat dissipation fins) and 430 (e.g., heat pipes).

[0035] In addition, the movable door (door member 412) of this embodiment is pressed against the peripheral side of the base 143 through the buffer member P1, and the main unit 410 is located inside the structure of the first surface S1 through another buffer member (i.e., buffer member P2) pressed against the base 143 and facing away from the aforementioned peripheral side. In this way, after the user opens the door member 412 from the main unit 410, the impeller 142 can be cleaned. This embodiment can effectively reduce the thickness of the main unit 410 through a single door member 412, so as to facilitate the thinness of the body.

[0036] In summary, in the above embodiment of the present invention, the notebook computer is provided with a movable door on the second surface of the main body, and the fan disposed in the main body is covered by the movable door. Accordingly, the user can easily operate the movable door to cover the fan or remove it from the fan, and after removing the movable door, the impeller of the fan can be exposed to the main body through the second surface, and the user can perform the required cleaning operation on the impeller, so as to improve the heat dissipation efficiency of the fan.

[0037] In one embodiment, the movable door can be composed of two door pieces, and one of the door pieces is pivotally connected to the main unit and the other door piece is pivotally connected to the base of the fan by a pivoting means, and the two door pieces are slidably coupled to each other on the side away from the pivoting end, so that the two door pieces can be pivoted open or pivoted closed synchronously. In one embodiment, the movable door can be composed of two door pieces, and the two door pieces are fixed together. The fixing means can be fixed by a column, a hole structure or a magnetic attraction according to the needs. However, no matter which one, it can successfully expose the impeller from the second surface with a simple structure.

[0038] In one embodiment, the movable door is only composed of a single door member, and the connection means between the door member and the host can be selected according to the aforementioned embodiments, and the second surface of the impeller can be exposed by opening the movable door.

[0039] In other words, due to the provision of the movable door on the second surface, the main unit can provide the user with a simple mechanism for cleaning the fan, and the user does not need to worry about affecting the operating feel and experience due to the complicated process of disassembling and assembling the main unit structure.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
